Early studies show that 3D printers may leave behind similar toolmarks on repeated prints.

    Re-slice in different positions, use a few different slicers and printers, got it. Thanks for the pro tip 👍🏻

      Just change nozzles every print, you can get cheap Chinese nozles for less than a $1 a pop.

      I think there was a study that showed every 3d printer leaves a sort of fingerprint, and they can identify which printer printed what object.

        In a lab, probably. In reality? No. Print nozzles wear over time and their patterns will change accordingly, and they are entirely replaced often.

        Won’t stop DAs from insisting on using it in court though.

        Yeah you can see the slop in the prints when the axis stops. You can just change print settings and it won’t look the same between prints. You can also use chemicals to smooth the outside of the print.
